Swift属于左侧预期编号列表

Question

我使用下面的代码来创建警报样式的规则列表 UIAlertController

let paragraphStyle = NSMutableParagraphStyle()
paragraphStyle.alignment = NSTextAlignment.Left
let messageText = NSMutableAttributedString(
    string: "1. Do not bully or target other users.\n2. Do not post others' private information.\n3. Do not post useless or offensive content.\n4. Do not post others' copyrighted content.\n5. Downvote and Flag posts which violate these rules.\n6. If you violate these rules, your account may be suspended and/or your content removed.",
    attributes: [
        NSParagraphStyleAttributeName: paragraphStyle,
        NSFontAttributeName : UIFont(name: "Lato-Regular", size: 13.0)!,
        NSForegroundColorAttributeName : colorAccentWords
    ]
)

它给了我警报视图,如下所示:
